Økologisk Rådgivning har i 2009 og 2010 gennemført forsøg med stigende mængde gødning til fire arter af vintersæd: vinterhvede, vintertriticale, vinterrug og vinterhavre. Forsøgene blev udført på lerjord, og forfrugten var korn eller kløvergræs. Forsøget indgik i en plan af to landsforsøg med stigende mængde gødning til fire arter af vintersæd med forfrugt korn. Planlagt tildeling af NH4-N/ha i de 5 led dækker over et spænd på 0 til 200 kg/ha. I det følgende bruges betegnelsen kvælstof (N) i betydningen NH4-N/ha, som er plantetilgængeligt kvælstof. |

Commercial potting media often contain substantial amounts of peat that was mined from endangered bog and fen ecosystems. The main objectives of this study were to assess (1) whether the amendment of 0, 20, 40, 60, 80 and 100% (vol/vol) of vermicompost (VC) to a fertilized commercial peat potting substrate has effects on the emergence, growth and biomass allocation of tomato seedlings (Lycopersicon esculentum Mill.) under greenhouse conditions, (2) whether possible impacts on seedlings can affect tomato yields and fruit quality even when transplanted into equally fertilized field soil, and (3) whether effects are consistent among different tomato varieties. Amended VC was produced in a windrow system of food and cotton waste mainly by earthworms Eisenia... |

The influence of site on resistance of grapevine (cv. Chasselas) to Plasmopara viticola was evaluated. Grapevine leaves from three vineyards in the region of Lake Neuchâtel (Switzerland) were tested for their susceptibility to P. viticola in the lab in five successive years (2004–2008), and the expression levels of four selected defence-related genes (Glucanase, Lipoxygenase 9, 9-cis epoxycarotenoid dioxygenase, Stilbene synthase) were studied in 1 year. In all 5 years of examination, differences between sites were substantial. In four out of 5 years, plants from site Hauvernier were much less susceptible to P. viticola than plants from site Auvernier. In another year, differences were less pronounced but still significant for one leaf age. Susceptibility... |

Phosphorus (P) is a limiting element for plant growth. Several root microbes, including arbuscular mycorrhizal fungi (AMF), have the capacity to improve plant nutrition and their abundance is known to depend on P fertility. However, how complex root-associated bacterial and fungal communities respond to various levels of P supplementation remains ill-defined. Here we investigated the responses of the root-associated bacteria and fungi to varying levels of P supply using 16S rRNA gene and internal transcribed spacer amplicon sequencing. We grew Petunia, which forms symbiosis with AMF, and the nonmycorrhizal model species Arabidopsis as a control in a soil that is limiting in plant-available P and we then supplemented the plants with complete fertilizer... |

Commercial potting media often contain substantial amounts of peat that was mined from endangered bog and fen ecosystems. The main objectives of this study were to assess (1) whether the substitution of peat by vermicompost (VC) in potting substrate affects the emergence and biomass allocation of tomato seedlings (Lycopersicon esculentum Mill.) under greenhouse conditions and (2) whether VC amendments in seedling substrate affect tomato yields and fruit quality after plants were transplanted into equally fertilized field soil. Amended VC was produced of food and cotton waste in a windrow system by Eisenia fetida Sav.. Vermicompost amendments significantly influenced, specifically for each tomato variety, emergence and biomass allocation (root:shoot ratio)... |

Vigorous seedlings are an important base for vegetable production. Beside the availability of appropriate amounts of nutrients, the health of seedlings is decisive. Soil-borne diseases are a challenging problem in organic seedling production. Here, we present results on the development of disease-suppressive growing media. Three aspects were examined: (i) use of different components of growing media (peat, coconut fiber, wood fiber, compost), (ii) influence of selected organic nitrogen fertilizers and (iii) use of different microorganisms (including commercial biocontrol agents (BCA)). Three plant-pathogen systems were used in this study: cucumber-Pythium ultimum, cress-Pythium ultimum and basil-Rhizoctonia solani. Green waste compost showed a good... |

Datensammlungen über die Zusammensetzung der pflanzlichen und tierischen Produkte, Dung- und Abfallstoffe werden vielfältig verwendet (u.a. Nährwertberechnungen, Bemessung der Düngungshöhe, Nährstoffbilanzierungen). Diese Tabellenwerke stammen allerdings aus konventionellen Anbau- und Bewirtschaftungsverfahren. Da bisher keine Alternativen vorhanden sind, werden sie oft auch für Berechnungen im ökologischen Landbau verwendet. Gegenüberstellungen von Produkten aus konventionellem und ökologischem Anbau haben aber Unterschiede in der Zusammensetzung der Inhaltsstoffe zwischen diesen Anbausystemen bestätigt (STOLZE et al., 2000). Das trifft besonders für die N-haltigen Inhaltsstoffe zu. Daher können Berechnungen für den ökologischen Landbau mit Hilfe dieser... |

Le potentiel suppressif de certains composts et de leurs extraits sur les maladies telluriques ou foliaires a souvent été démontré. L’efficacité des composts et/ou des extraits varie en fonction du type de compost et du système plante hôte-pathogène. Les raisons de cette variabilité demeurent encore en grande partie méconnues. De plus, les mécanismes d’inhibition des pathogènes par les composts et/ou les extraits de composts restent encore insuffisamment explorés. Une meilleure connaissance des paramètres influençant les propriétés phytosanitaires des composts et de leurs extraits est donc indispensable afin de pouvoir optimiser leur utilisation pour lutter contre les maladies des plantes. Les objectifs du présent travail visent (i) la caractérisation des... |

Ergebnisse der von 2011-2017 laufenden Versuchsserie mit 76 Einzelexperimenten zur Entwicklung eines standardisierten Biotests für das Hornmistpräparat, die in Kooperation mit der biodynamischen Koordinationsstelle an der Universität Kassel Witzenhausen auf dem Dottenfelderhof durchgeführt wurde. Untersucht wurde, wie sich die Wurzellänge von Kressesamen unter Einfluss des Hornmistpräparats entwickelt. In 28 von 76 Fällen wurde das Wurzelwachstum signifikant beeinflusst. Jedoch ist die Wiederholbarkeit der Ergebnisse über lange Zeitperioden schwierig. Das Potenzial von Laboruntersuchungen zur Wirkweise der biodynamischen Präparate wurde aufgezeigt und sollte weitergeführt werde. |

A study was conducted which aimed to investigate the effect of farming systems (FS) (four conventional with increasing mineral N fertilizer amounts 0–150 kg of N ha−1) vs. two organic with catch crops (CC) and cattle manure (CC+M)) under the same five crop rotation system on the occurrence of tuber diseases such as common scab (Streptomyces spp.), silver scurf Helminthosporium solani), dry rot (Fusarium spp.), and soft rot (Pectobacterium spp.). As the average of the first rotation years 2009–2011, the FS had a significant effect on the occurrence of silver scurf, dry rot and common scab (surface cover <30 %). The organic systems had significantly more tubers (around 39 %) infected with common scab (surface cover 4–15 %) than in conventional systems... |
